METHOD AND SYSTEM FOR OBTAINING PRODUCTS, INCLUDING ALCOHOLS AND/OR ACIDS, IN MICROBIOLOGICAL FERMENTATION

摘要

FIELD: chemistry.SUBSTANCE: inventions relate to field of biotechnology, namely to method and system for obtaining one or more products, including alcohols and/or acids, by means of microbiological fermentation. Discontinuous or inconstant flow(s) of CO-containing flue gas or offgas is received from production process into storage reservoir. Substantially continuous flow(s) of gas from storage reservoir is (are) directed into bioreactor, which contains culture of one or more carboxidotrophic bacterium in nutritional medium. Said culture is fermented with obtaining one or more products, including alcohols and/or acids. System for obtaining one or more products, including alcohols and/or acids, contains input for reception of discontinuous or inconstant flow(s) of CO-containing flue gas or offgas, storage reservoir for reception of said gas flow, made with possibility of directing said gas flow in substantially continuous mode into bioreactor. System is made with possibility of directing at least a portion of said gas into bioreactor.EFFECT: inventions make is possible to use inconstant in its nature flows of gaseous substrate and ensures achievement of such substrate flow continuity when it is supplied into bioreactor.7 cl, 17 dwg, 5 tbl, 2 ex
